Re: [Plug] followup.. BIND question...

In standard mode, when you connect to a site via ftp, you connect to
port 21. When you do an "ls" the server you're connected to attempts to
connect back to you on port 20 (a privliged port). If you're behind a
firewall or proxy that doesnt allow this then you'll get the error
you saw. Passive mode is essentially telling the ftp server to keep
all traffic on the same port.
At least I think those are the port numbers. Its been a while, but
anyways the explanation is technicaly correct.
ftp> help
Commands may be abbreviated. Commands are:
! debug mdir sendport site
$ dir mget put size
account disconnect mkdir pwd status
append exit mls quit struct
ascii form mode quote system
bell get modtime recv sunique
binary glob mput reget tenex
bye hash newer rstatus tick
case help nmap rhelp trace
cd idle nlist rename type
cdup image ntrans reset user
chmod lcd open restart umask
close ls prompt rmdir verbose
cr macdef passive runique ?
delete mdelete proxy send

When I grow up, I wanna be more like me.
I had a clue. I didn't like it. I took it back and exchanged it for an
attitude.
